Problem 2BSC

Rank Sum After ranking the combined list of 24 arrival delay times, find the sum of the ranks for Flight 19.

Solution 2BSC

The combined sample of 24 values are assigned the ranks neglecting the signs of the values, in the order that the least value is assigned the rank as 1 then a value which is just greater than the previous one is assigned the rank 2 and so on , if there is a tie then mean of the ranks is found and each such value is assigned the mean rank. As shown below:

Flight 19 -5 32 -13 -9 -19 -49 -30 -23 14 -21 -32 11

Rank() 2.5 18.5 7 4 10.5 22 17 13.5 9 12 18.5 5

Flight 21 -23 28 103 -19...
